OVERVIEW

Applied Geophysics studies the distribution of the physical properties in the shallower solid Earth by non-invasive methods. It is a fundamental part in the exploration of energy, mineral and hydric resources and has geotechnical and environmental applications.

LEARNING OUTCOMES

The course provides a general introduction to the basic principles of geophysical exploration and monitoring. An overview is furnished about geophysical signal elaboration and the most important applied methods on subsoil investigation, instruments and physical parameters of the geophysical prospecting and a first approach to data processing and their geological interpretation.

AIMS AND LEARNING OUTCOMES

Attending the activities, the student will get the general knowledge of the geoelectrical and seismic refraction methods necessary in the Earth sciences for technical consultancies and scientific researches.

The student will be able to:

• to know and describe the geoelectrical and seismic refraction methods
• to select the right study methods to solve specific problems
• to interpret measurement results and show them qualitatively and quantitatively

PREREQUISITES
